摘　　要：为了提高固废在制备发泡陶瓷中的利用率,利用不同固废的特性协同制备发泡陶瓷。以钼尾矿为主要原料,粉煤灰、废玻璃粉和白云石为辅料,SiC为发泡剂制备发泡陶瓷。研究了粉煤灰、废玻璃粉和白云石的添加量对样品外观形貌、孔径、气孔率、体积密度、抗压强度的影响,并分析其影响机理。结果表明,最佳组分为52.5%钼尾矿,25%粉煤灰,15%废玻璃粉,7.5%白云石,此条件下发泡陶瓷体积密度为0.519 g/cm^(3),气孔率为62.96%,抗压强度为9.666 MPa。加入粉煤灰可促使长石类矿物的生成,其与石英交织,制备出的发泡陶瓷质轻高强,可用作建筑中的轻质隔墙板。In order to increase the solid waste utilization efficiency in foamed ceramics,the characteristics of different solid wastes are used to make foamed ceramics,with molybdenum tailings as the main material and fly ash,scrap glass powder,and dolomite as auxiliary materials.The results showed that the optimal addition amounts of foamed ceramics were found to be 52.5%molybdenum tailings,25%fly ash,15%glass powder,and 7.5%dolomite,resulting in a bulk density of 0.519 g/cm^(3),porosity of 62.96%,and compressive strength of 9.666 MPa.The addition of fly ash promoted the formation of feldspar minerals,which were interwoven with quartz to prepare lightweight,high-strength foamed ceramics,which could be used as lightweight partition panels in construction applications.
